Types

type Receiver

type Receiver struct {
	// IsolatedTx causes Ordered returns [][]{curBatch, []{newTx}}, false when set to true
	IsolatedTx bool

	// CutAncestors causes Ordered returns [][]{curBatch}, true when set to true
	CutAncestors bool

	// CutNext causes Ordered returns [][]{append(curBatch, newTx)}, false when set to true
	CutNext bool

	// CurBatch is the currently outstanding messages in the batch
	CurBatch []*cb.Envelope

	// Block is a channel which is read from before returning from Ordered, it is useful for synchronization
	// If you do not wish synchronization for whatever reason, simply close the channel
	Block chan struct{}
}

Receiver mocks the blockcutter.Receiver interface

func NewReceiver

func NewReceiver() *Receiver

NewReceiver returns the mock blockcutter.Receiver implementation

func (*Receiver) Cut

func (mbc *Receiver) Cut() []*cb.Envelope

Cut terminates the current batch, returning it

func (*Receiver) Ordered

func (mbc *Receiver) Ordered(env *cb.Envelope) ([][]*cb.Envelope, bool)

Ordered will add or cut the batch according to the state of Receiver, it blocks reading from Block on return
